Abstract. The material was collected between 2017 and 2020 during all seasons. Following methods were used: 1. Actively searched in proper habitats, and collected by wet brush; 2. Sieving with 1 mm mesh width sieve of detritus or crushed bark particles above white plastic container; 3. Beating the vegetation above white plastic container; 4. Checking for dead individuals in spider webs or paddles full with water; 5. Sweep netting of vegetation; 6. Trapping by white plastic containers placed below lamps. There were 9 species of Psocoptera known from Sarnena Gora Mts. till present study. After the detailed research a total of 35 species of Psocoptera are known to occur in the area (26 newly recorded species). The species petersi was a new record for Bulgaria.

Key words: Insecta, Psocoptera, localities.

Introduction There were 9 species of Psocoptera known from Sarnena Gora Mts., all reported by the author (Georgiev 2016, 2017a, 2017b, 2018): Lepinotus reticulatus Enderlein, 1905, Lepinotus inquilinus Heyden, 1850, Liposcelis bostrychophila Badonnel, 1931, Liposcelis pearmani Lienhard, 1990, Liposcelis priesneri Enderlein, 1925, Liposcelis silvarum (Kolbe, 1888), bernardi Badonnel, 1938, Ectopsocus vachoni Badonnel, 1945, and Cuneopalpus cyanops (Rostock, 1876).

Here I summarize all published data and present some new records of barkfly species and their localities in this area.

Material and Methods The material was collected between 2016 and 2020 by following methods: 1. Actively searched in proper habitats, and collected by wet brush; 2. Sieving with 1 mm mesh width sieve of detritus or crushed tree bark particles above white plastic container; 3. Beating the vegetation above white plastic container; 4. Checking for dead individuals in spider webs or paddles full with water (Fig. 1); 5. Sweep netting of vegetation; 6. Trapping by white plastic containers placed below lamps. Specimens were then stored in ethanol and after processing, deposited in the collection of the author. Most of the material was collected by the author. Some samples were provided and by Assist. Prof. Miroslav Antov (Plovdiv University), which is mentioned in the text. Species identification and taxonomical order follow Lienhard (1998) and Lienhard & Smithers (2002). As a supporting source, Saville (2008) was also used.
